This is right, for as long as the fdm printer hobbyists can avoid the lockdown and enshittification that some printer brands are definitely pushing. The value of this paper, for it’s authors, seems more like a proof of concept: fingerprinting is possible. And I think that’s actually it’s same value for hobbyists: the problems with a closed system and proprietary printer firmware are not hypothetical.

The fact that this could only work in 100% locked down ecosystems was my thought too. About cutting the part up, that seems to be what this particular paper is most proud of: they did a bunch of math to make some codes that they could still figure out even when they were cut into pieces and mixed up—like if a person broke their printed part after using it. Sort of like error-correcting codes I guess, but able to be reassembled from fragments.

Here’s the paper where they explain it. Basically, they make subtle fluctuations in layer height, adding or subtracting small amounts that are not visible to the naked eye, to encode 0s and 1s. So, maybe in principle this could run at the firmware level on your printer. Then, someone can use a microscope to read off the code from pieces of the printed part.
I would have some doubts about how reliable this is, given the relatively large tolerances in fdm printing, but they have a section about that in the paper, so I guess they at least have thought about it.

Yep. If it’s 9:22:45, then rounding to 9:23 is more accurate than 9:22 anyway.

Thanks! I wondered about the glue stick trick, but I think you’re right that a taper would be better. I have to wonder why he didn’t say that, but maybe he was tight on time or some other thing.

The part at the end about the fins is good, but too quick. He says put a gap under the fins, and that makes sense, but then how do they print? Are they small enough that they can basically just break away? I’ve heard ironing is the key to stacked, separable prints (like miltiboard grids). I’d that (a) necessary, (b) unnecessary but helpful, or © irrelevant for these fins?
P.s. while I was internet searching to try to understand this, I found a cute video of his from 3 years ago where he is explaining the same concept, but with less polish and less good vtuber equipment. Still neat, and neat to see how he has and hasn’t changed over time.

Lol, I bet you can figure it out.

Shout out to OP for recognizing the struggle and respecting the rule (I thought this was a 196 post at first!)
Men will lurk for years without ever commenting in some communities, and then (ITT) lose their minds when confronted with the possibility of a community they are welcome to read, but asked not to comment. Bros, you were already doing that!! Yes, it’s hard, that’s what this post is about. But you can do it!!
- Comment on [deleted] 1 month ago:
Lol, I wasn’t going to chime in to this train wreck, but this is awesome. Hi Langara! I hope you learn what not to do here. Also worth noting: it’s easy, and good, to see how stupid the olds can be. It’s harder, by a lot, to see which new things are stupid in a new way (or newly packaged way). Good luck.

- Comment on "I have been collecting the little tricks and rules for designing well-printable parts" 1 month ago:
Like others have already said, this article is a good collection of tricks/principles/examples. There are also lots of links out to other resources that cover the various items in more detail.
But I haven’t seen anyone mention how awesome that head image is! Take a closer look if you didn’t at first. I’d love to see an animation that wipes from design to completed piece.
- Comment on What are your go-to sites to find free 3D files to print? 1 month ago:
None of the sites are completely free from enshittification, but printables seems the least bad. Prusa has a better track record with supporting an open community, at least for now. Bambu+makerworld is an example of a company trying to close as much as possible to lock people in. Now I can’t download without a login? No thanks.

Yeah, there’s probably all kinds of clever ways to use folding for subdividers or something. If you come up with something to post, tag me so I can check it out!
- Comment on foldable organizer walls 1 month ago:
Yeah! I know people make full organizer models for it, but mine has grown into its own thing over time, as I add more parts for the new expansions.

- Comment on made this functional part to fix a broken latch 4 months ago:
I like the sustainability, but if I’m being honest, what I really enjoy is the pure satisfaction of solving a tiny but annoying problem. This was a lot cheaper than a full replacement, but also a lot easier than tracking down the part and ordering it.

This is petg with 100% infill, and it seems sturdier than the original. I put a reminder for myself to check in 6 months if I don’t notice a problem sooner.
